Thank you. your 7.34 duration video is thousands time better than my 1hour class lecture

[@shreyashk246]

100%

[@GATEWith_HARIS]

sir during polynomial division does this division does not follow math rule ? means sign like in first time division +X^4 is left as positive but according to conventional method of division it should -X^4 I am so confused plz help

[@JAcademy]

Yes it does

[@shwetahegde8850]

Thanks. Nicely Explained

In 4:29 of the video x^6 + x^3 subtract x^6 +x^4+x^3 should result in -x^4 and not x^4 could you check please?

[@wimblesoft]

This is not a regular subtracting. We are not writing minuses in results of subtracts.

[@muntaha0019]

The creator of this video used modulo-N arithmetic or simply XOR those values.

[@TecICTian]

This is very clear, I shared it!

[@JAcademy]

Thanks for your lovely comment

[@AshishShukla-ro8oy]

i think division is wrong .....remainder after the 1st step will be - x^4 not x^4 and same so on....

How do you know the generator code appropriate of the message code?

[@fadye.f.samann4720]

"Wireless Communication
Networks and Systems" by Cory Beard, page 125
r is the length of the FCS. This means there are 2^r possible error patterns, and
only one of those patterns will go undetected.
Four versions of P(X) have been widely used
CRC-12 = X^12 + X^11 + X^3 + X^2 + X + 1
CRC-16 = X^16 + X^15 + X^2 + 1
CRC-CCITT = X^16 + X^12 + X^5 + 1
CRC-32 = X^32 + X^26 + X^23 + X^22 + X^16 + X^12 + X^11
+ X^10 + X^8 + X^7 + X^5 + X^4 + X^2 + X + 1
the CRC-12 system is used for transmission of streams of 6-bit characters and generates a 12-bit FCS. Both CRC-16 and CRC-CCITT are popular for 8-bit characters,
in the United States and Europe, respectively, and both result in a 16-bit FCS. This
would seem adequate for most applications, although CRC-32 is specified as an
option in some point-to-point synchronous transmission standards.

What if my message is 55x^3+49x^2+23x+12?🤔🤔

[@adityaj7664]

it cant be right? the coefficients have to be 0 or 1. They represent the values at the positions in the bit expression

[@avinashbalakrishna1927]

I could not understand your subtraction... How did you cancel two same sign quantities?

[@JAcademy]

Its XOR not algebraic division

[@ITExpertZone-IT]

@@JAcademy YES IT'S A SUBTRACTION METHOD IN POLYNOMIAL.........IN ADDITION ALSO SAME TERMS CAN BE CANCEL......THERE IS NO METER OF SIGN HERE.....YOU ARE RIGHT.

[@ssaahil0111]

helpful!

[@suaibislam2923]

No, It's correct. He didn't subtract rather did xor.
